Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the deivce may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed speci-
fications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.
Note 2:
All voltages are specified with respect to ground.
Note 3:
When the input voltage (V
) at any pin exceeds the power supply voltages (V
<
V
or V
>
V
+
) the absolute value of the current at that pin should be
limited to 5 mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply voltages with 5 mA current limit to four.
Note 4:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
,
θ
, and the ambient temperature T
. The maximum
allowable power dissipation is P
D
= (T
JMAX
T
A
)/

or the number given in the Absolute Maximum Ratings, whichever is lower. For the LMC1983CIN, T
JMAX
=
+125C, and the typical junction-to-ambient thermal resistance, when board mounted, is 67C/W.
